| 中文摘要: |
| 考虑现实网络中流的分布式传输方式和边的负载-容量关系，提出了一个带有可调权重参数的边级联失效模型.依据新的度量网络鲁棒性指标，探讨了两种典型复杂网络由蓄意边攻击而引发的级联失效行为.仿真结果表明，存在最优参数值使得网络达到最强抵制边级联失效的鲁棒性，能够显著降低灾害动力学发生的可能性.而且，网络的拓扑结构和平均度均对网络鲁棒性产生了影响。 |

| Considering distributed transmission mode of flow and load-capacity relation for edges in real networks,an edge cascading failures model with a tunable weight parameter is proposed.According to new measures to the robustness of a network,cascading failures triggered by intentional edge attacks on two typical complex networks are investigated.The simulation results show the existence of optimal parameter value corresponding to the strongest robustness achievement for the networks against edge cascading failures,reducing significantly the likelihood of the occurrence of catastrophic dynamics.Furthermore,topological structure and average degree of the networks all have effect on the network robustness. |
